Don't need to think about bigger injectors till you climb above 350rwhp. Cam, programmer, headers,exhaust, CAI, are all good with the stock injectors. If you go to ported heads then it may be time to look at them. You have an 06 with the MDS, KRCPerformance has some mds friendly cams forsale. If you go for one, anything above there first or second choice will require additional programming which can be tricky to deal with.

I also hear 4:56 gears and the 20's also wake things up, I'm told as much as a converter will do. Combine them for some tire shredding goodness.
